Bridge demolition to close all US-280 lanes at Pump House Road in Mountain Brook

Major lane closure planned for US-280 at Pump House Road.
ALDOT plans to close all US-280 lanes at Pump House Road the weekend of March 20-22.
Mar 10, 2026

ALDOT will close all lanes of US-280 at Pump House Road to complete necessary bridge demolition in the highway’s ongoing widening project.

Beginning at 11 p.m. on Friday, March 20, weather permitting, crews will close all lanes of US-280 in both directions at Pump House Road.  Eastbound lanes will remain shut down through the morning of Monday, March 23.  Westbound lanes will reopen each morning at 5 a.m. before closing again at 11 p.m. 

Crews will reopen all lanes of US-280 at Pump House Road no later than 6 a.m. on Monday, March 23.

These lane closures mirror those used to install the first three Pump House Road Bridge girders in November.

Crews installed the first three of five girders for the new Pump House Road Bridge in November.

The demolition is essential to widen US-280 to four lanes in each direction from Lakeshore Parkway to I-459.  

Crews will spend the next two weeks demolishing the old Pump House Road Bridge.

Major delays are expected, and ALDOT encourages travelers to begin planning alternate paths through this corridor now.

We recommend motorists use Lakeshore Parkway to I-65 to I-459 to US-280 as a main detour heading east and the reverse route order for westbound trips. (See attached detour map)

There will be one additional weekend of total road closures to complete the bridge construction in the weeks ahead.

ALDOT thanks the public for their patience during this project to greatly increase US-280 capacity when completed this fall.
